|Route outline (key)|
The B4287 is a short, largely rural B-road running southeast from Neath.
It starts at traffic lights on the B4434 (former B4288), at the point where Victoria Gardens becomes Eastland Road, and heads out of town through the suburb of Cimla. The route climbs to a summit near playing-fields at Cefn Saeson, then descends steeply to the village of Efail-fach. Here it crosses the Pelenna and follows that river downstream to its confluence with the Afan in Pontrhydyfen.
Shortly after passing the end of the B4286 from Port Talbot, the B4287 goes under a railway viaduct (now disused) before immediately bending right to cross the Afan River and climbing to a T-junction on the A4107.
